If you've ever dealt with a stuck garage door that won't budge, springs are likely the culprit. Garage door springs in Mountlake Terrace come in two main types: torsion and extension. Understanding which one your door uses, how they work, and when they need replacing can save you money and frustration.
Springs are the hardworking components that counterbalance your garage door's weight. Without them, opening a 300 to 400 pound door by hand would be nearly impossible. Your garage door opener motor only works because the springs do the heavy lifting. They store and release energy with every cycle, which means they wear out over time. See our guide on garage door won.
Most residential doors in Mountlake Terrace use one of two types. Torsion springs wind around a shaft above the door opening and twist to lift the weight. Extension springs run along the sides of the door frame and stretch to provide lift. Both systems work well, but they behave differently and fail in different ways.
Torsion springs are the most common choice for modern garage doors. They're mounted horizontally above the door, coiled around a metal rod. When your door opens, the springs wind tighter, storing energy. When you close it, they unwind, releasing that energy to lower the door smoothly.

The biggest advantage of torsion springs is balance. Because they work at the center point of the door, they provide even weight distribution. This means less strain on your opener motor and smoother operation overall. A typical torsion spring lasts 7 to 9 years with regular use, handling 10,000 to 20,000 cycles before needing replacement.
When a torsion spring snaps, the door becomes extremely heavy and dangerous. You'll hear a loud bang from the garage. The door won't open without the opener straining hard. If this happens to you, stop using the door immediately and call a professional. Learn more about what to do in our guide to snapped garage door springs in Mountlake Terrace).
Extension springs are an older design still found on many homes. They run vertically along both sides of the door frame, stretching as the door opens. A pulley and cable system transfers their force to lift the door.
Extension springs take up less overhead space than torsion systems, which makes them popular in garages with low ceilings. However, they require safety cables to prevent injury if a spring breaks. Without those cables, a snapped extension spring can whip across the garage at dangerous speeds.
Extension springs typically last 4 to 6 years. They handle fewer cycles than torsion springs, usually around 10,000 total before wearing out. If you're comparing cost and longevity, torsion springs offer better value over time, though installation is slightly more complex.
